Daily Update: Using the adding machine on Chase Headley

We offer these daily updates on Chase Headley because the numbers are almost off the charts.

In the 43-season history of the Padres, only one San Diegan ever led the National League in RBI – Dave Winfield with 118 in 1979. Sunday’s grand slam against Arizona has moved Headley into the National League RBI lead with 102.

Let’s start by addressing the RBI:

-- Headley’s season is only the 18th 100-RBI season in Padres history -- and the fifth since pitcher-friendly Petco Park opened in 2004. The club RBI record is 130 by Ken Caminiti in 1996. The Padres high during the Petco Park era is 119 by Adrian Gonzalez in 2008. Headley’s 102 RBI already ranks 14th on the all-time Padres list.

--Headley has 60 RBI since the All-Star break and 50 since Aug. 1.

--His 60 RBI since the All-Star break is tied for the second-highest mark in Padres history. Padres hitting coach Phil Plantier had 60 RBI after the All-Star break in 1993. The club’s post-All-Star break RBI record is 81 by Ken Caminiti in 1996.

--And the 50 RBI since Aug. 1 have come in 36 games, including 14 RBI in eight games in September.

The grand slam was Headley’s 19th since the break . . . and his 15th since Aug. 1.
